49ers will place Crabtree on PUP list

The date of Michael Crabtree’s return remains uncertain, but his injury designation is no longer a mystery.

Jim Harbaugh said the 49ers plan to place their No. 1 wideout on the active physically unable to perform list this week. The team can place Crabtree on the reserve PUP list after the final roster cuts of training camp and he will be sidelined for the first six weeks of the season. The 49ers could activate Crabtree at any point between Weeks 7 and 13. In Week 13, the 49ers host the Rams on Dec. 1.

Harbaugh gave an optimistic update on Crabtree, who, he noted, has stayed in town to rehabilitate the torn Achilles he sustained May 21.

“Talking to the doctors and talking to Michael, they feel very good about where he is right now,” Harbaugh said. “I wouldn’t categorize it as ahead of schedule because he’s just starting now to start moving on it. It’s healing, but it looks greats. That’s from the words of the doctors.”

** Perhaps you’ve heard: Colin Kaepernick was photographed wearing a Miami Dolphins cap earlier this month, responded defiantly on Twitter to those who objected and there was a resulting stream of breathless headlines.

Today, Harbaugh was asked about Kap-Gate.

“I know Kap,” he said. “I know where his allegiances lie. They lie with us. I chalk that up to a slow time in the media cycle. I know exactly where his allegiances are.”

** On a personal note, thank you for the stream of kind comments and e-mails in response this blog about my late mom. I initially wondered if this was the proper forum for such a tribute, but I have no regrets. Thank you.
